Strengths/Achievements Strongest vocalist in f(x) One of the most developed head voices amongst female K-pop vocalists Achieved resonance a number of times from G4 ~ E5 range Able to mix up to A5 Able to keep a stable larynx even in her lowest notes Able to project forward her lower register range between B3 ~ G3, occasionally F#3’s and F3’s Consistent with resonance and placement, very good placement on belts Very relaxed and healthy vibrato Head placed studio A5 in mixed voice Big improvement since debut Weaknesses Loses consistency on E5’s, and strains anywhere from F5 or above At times tends to get nasal mid-phrases but not in belts Tongue tension and pulling sound back in placement may happen at times Notes below G#3/G3 tend to be very quiet and a bit too airy May present vocal fatigue during a song that requires a lot of belting throughout the whole song Head voice may be resonant but isn’t as often showcased as she could Runs at times may be sloppy and slow Pitch and Intonation are not completely consistently on point Nasality may be present in her head voice Transitions between mix and head show a lack of control in head voice pitch wise Registers Lower register: at times able to produce well and full notes down to F3 and F#3 but may lose consistency in keeping cord connection down there. Consistently able to produce supported notes from G3 and above, whereas notes below F3 generally become very quiet and breathy. Mixed register: Very well balanced mix, not too much chest and generally bright and yet resonant. Placement is often kept well and opened during belted notes up until D5 and at times Eb5 live, and consistently up until Eb5 in studio. Live and in studio she’s been able to produce resonant E5s but not consistently and anything above E5 has a tense high larynx. Nasality may be present in this register. Upper register: Notes in her head voice are mostly very pure and bright, very well produced without breathiness. She has projection, cord connection and is able to articulate well in this register, but may often confuse mask placement with nasal placement in her head voice. Able to produce resonant and relaxed notes up until Bb5. Agility

Luna’s voice is a very light soprano voice with a brightness to it. One of her biggest weakness is her lack of vocal agility. Her runs are often slow and sloppy, lacking note precision. She doesn’t often sing R&B nor does runs, but when she tries to add them to a melody they sound slightly off and flat, without fully having a thought-process before hand to plan them out and practice them fully so that they hit every single note precisely. She does not usually show an ability to do runs that are faster than a slow-tempo one, but occasionally is able to precisely separate each single note in her vocal runs, specially in her head voice, such as in “해뜬날“.

Overall analysis

One of the most capable vocalists amongst SM vocalists and in general, the newer generation of female idol groups, Luna is a one of a kind vocalist. She may not have the prettiest tone out there, but starting off as a dancer turned main vocalist, she’s been able to show great improvement from her debut days till present. Luna possesses a light bright soprano voice, with a very youthful feminine color to it. It retains a clean sound throughout her range and presenting technical control superior to most other main vocalists.

Luna’s lower range is one that shows an impressive amount of development in comparison to the average female pop vocalist. Most of the time she’s able to keep a stable larynx in her lower range and although breath
